National Trust Headquarters
Trapezoidal in shape, the exterior of the National Trust’s new central offices, with the exception of the south facing glass façade, is clad in blue engineering bricks and features Limetec® hydraulic lime mortar – a modern day replica of hydraulic lime mortar. As well as meeting the client brief by eliminating the need for cement and offering recyclable qualities, lime mortar offers a number of other advantageous properties. With the dexterity to accommodate slight movements in the building caused by settlement or thermal shock without cracking, it reduces the need for expansion joints. It also remains workable for up to 24 hours, has a long-proven performance, offers enhanced aesthetics over similar products and is breathable. As part of a sustainable building design, these properties can help to create a major reduction in a building’s carbon footprint. To create a comfortable interior environment, Feilden Clegg Bradley also ingeniously used the exterior brickwork as a method of providing solar shading and preventing heat gain within the building. By creating a series of brick fins, which gently protrude alongside the recessed glazed sections, they stop direct sun from hitting the glass and heating the building, while ensuring maximum natural light enters the office space.
The National Trust’s new central office is an inspirational example of what can be achieved in large scale, new building projects, using sustainable materials. Limetec has created a solution that enables mortar to be created in bulk on site. Using an innovative silo mixing station, which can store up to 35 tonnes of dry material, ready mixed mortar can be produced at the simple touch of a button. This not only guarantees mix proportions and supply, but also eliminates wastage, again reinforcing it as a highly environmentally friendly product.
